CNContactViewController hides navigation bar

Question

When I click CNContactViewControlleron the stack of the subclass UITableViewControllerthat is inside UINavigationController, the top navigation bar is almost completely hidden. But with full brightness, you look at the back arrow, and then the word "Detail" and the system status bar. When I touch this corner of the screen, the CNContactViewController really deviates.

Of course, this is bad, because the user probably will not even see the text of the navigation bar and will now press any buttons to reject.

Is there a way to make the hue of the CNContactViewController navigation bar the same as the display controller that showed it (the rest is my application)?

CNContactViewController *controller = [CNContactViewController viewControllerForUnknownContact:person];

controller.contactStore = [[CNContactStore alloc] init];
controller.delegate = self;
controller.allowsActions = NO;

[self.navigationController pushViewController:controller animated:YES];
